Cloud Dynamic User Groups (CDUGs) are the Cloud Identity Engine capability purpose-built for exactly this use case: rather than relying on a static, manually maintained group whose membership must be updated by hand whenever a user ' s role, department, or other Entra ID attribute changes, a CDUG defines membership criteria based on directory attributes or context - department, title, location, risk score, or other Entra ID fields - and continuously, automatically re-evaluates which users belong to the group as those attributes change. Once created, the resulting group receives an auto-generated distinguished name that Prisma Access recognizes and can reference directly as source identification within a Security policy rule, giving administrators attribute-driven, self-maintaining access control rather than a fixed group membership list. This makes option D the correct capability. " Entra ID Group Attribute " and " Entra ID Cloud Group " (options A and C) are not the names of actual Cloud Identity Engine features; they resemble plausible terminology but do not correspond to a distinct, documented capability distinct from Cloud Dynamic User Groups. " Attribute Group Mapping " (option B) similarly does not exist as a named capability in the Cloud Identity Engine; while group mapping in a general sense is a core CIE function for synchronizing static directory groups, the specific capability that lets a Security policy dynamically use Entra ID attributes as the basis for group/source membership is the Cloud Dynamic User Group, not a generic " attribute group mapping " construct.
